Bad news out of Dayton, though it could have been much worse:

Four people were wounded after a shooter opened fire at a Walmart near Dayton, Ohio, before taking his own life Monday night, police said.

The suspect, described only as male, entered the store around 8:35 p.m. and shot four people before turning the gun on himself, Beavercreek police said. He died of an apparent self-inflicted gunshot wound, according to the department.

One eyewitness claimed that the shooter had an "assault rifle" (because that's the only term people know anymore for "scary gun") and fired at least 10 shots during the incident. Police have not indicated if the weapon was a semi-automatic pistol or rifle or what caliber the shooter used during the attack.

On Tuesday morning police had still "not identified the suspect" and it was "unclear if he knew any of the victims at the store in Beavercreek." Responding officers had not fired any shots during the incident, according to media reports.

The FBI, the Bureau of Alcohol, Tobacco, Firearms and the Explosives and Ohio Bureau of Criminal Investigations were all reportedly investigating the incident on Monday.

Walmart, meanwhile, said in a statement that it was "heartbroken" over the shooting and was working with law enforcement on the scene.
